Fluid2 Trainer Smart Equipped

Saris takes its top-selling trainer in the USA and adds a dual-band ANT+ and Bluetooth speed sensor so you can reap the benefits of virtual training via apps like Zwift and Rouvy. The fluid resistance unit is quiet (64-68 decibels at 20mph), and offers a progressive power curve that increases the resistance as you shift gears and pedal harder—just like if you were on the road.

The Fluid 2's roller features a clutch knob that ensures perfect roller-to-tire tension every ride, reducing tire wear and slippage. The precision-balanced flywheel doubles as a fan so no matter how many watts you produce the resistance is stable and the unit stays cool. The wide, stable base adds security on any surface, and asymmetrical leveling feet ensure you'll always be balanced. The rear wheel mounts easily and a simple bolt-action lever tightens the resistance unit around the skewer, meaning you won't have to readjust your bike every time you put it on the trainer. Sprint, jump out of the saddle, and time trial without the worry that you'll pull the rear wheel out of the trainer.

The CycleOps Fluid 2 Trainer will accommodate tires from 26 to 29-inches with rear spacings of 120, 130, and 135mm. An optional thru-axle adapter for 12 x 142mm and 12 x 148mm spacing is available separately.
